To (LZZ whont it may concern:

Be it known that I, ERNEST CHAPIN COLE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have made certain new and useful 1 Improvements in Creosote-Traps,- of which the following is a specification.

My invention is an improvement in stoves and ranges, and has for an object to provide a novel means whereby to catch and retain creosote dropping from the smoke-pipe of a range; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a back cast-iron flue of a range, partly broken away to Show the creosote-pocket. Fig. 2 is a vertical section on about line 2 2 of Fig. 3, and Fig. 3 is a cross-section'on about line 3 3 of Fig. 2.

AS shown in the drawings, the back cast iron flue A may be of ordinary form, and it may be connected up with the range-body B and with the ofltake pipeor flue in any suitable manner. An opening B leads from the body of the range into the flue A. This flue A is provided at its lower end with a pocket A below the outlet-opening B, in which the creosote dropped from the smoke-pipe of the range will be retained until it is evaporated by the direct drafts of the stove when such drafts are opened. This prevents the creo I sote from coming in contact with the sheetsteel of the range-body, which is recognized as one of the causes of the rapid destruction of steel ranges. In securing the pocket A it is preferred to provide the flue A at its inner side with the integral upwardly-projecting plate A whose lower edge coincides with the lower edge of the outlet opening B for the passage of the products of combustion from the range -body, so that the creosote will drop into and be retained in the pocket formed at the lower end of the flue A below the line of the outlet-opening B This is an important feature of construction, as by it the pocket or trap is formed in the casting of the back flue and all dangers of leakage resulting from defective joints and the like are avoided.

It will be noticed that the back flue A is open at its inner side and is flanged, so that such inner side may be secured snugly against the plate B of the range-body, and

the upwardly-projecting plate A at the inner side of the flue A forms the integral pocket at the lower end of said flue, as best shown in Figs. 1 and 2 of the drawings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The back flue and creosote-trap for ranges herein described, consisting of a comparatively flat cast-iron body Open at one side and formed at said side with its edges in a flat plane, and having along its side edges and bottom an outwardly-projecting flange also in the flat plane of the open face of the body and having at its lower end at its open side an upwardly-projecting flange forming a pocket at the bottom of the body, the said upwardly-projecting flange having its outer face coincldent with the corresponding-face of the outwardly-projecting flange of the body whereby the trap may be fitted flat against a flat back plate of a range-body, and the outwardly-projecting flange and upwardly projecting flange will coincide in l their abutment with said body and the pocket at the bottom of the body and operate as a trap for creosote substantially as and for the purposes set forth.

ERNEST CHAPIN COLE.
